Young Israel of Westside Shiurim

1. R shimon be Yochai did kind deed for the community. There was a road where doubt occurred about whether dead bodies were buried there and kohanim couldn’t go. RASHBI fixer this issue. He killed someone who ridiculed him and he also killed the person who originally told on him 2. B4 Shabbos a person should say in his house- did you tithe? Make eiruv? Light candles. He should say these things gen...

1. For wrong judgement and bitul Torah, the Jews will be invaded and famine will come. 2. False paths and chillul Shabbos and Hashems name, wild beasts willl increase and cattle will be destroyed 3. For sins of murder, the Beis Hamikdash will be destroyed and the Shechina will leave. 4. For immoral relations, and not keeping shemita/yovel, the Jews are exiled 5. For bad language, calamities befall...

1. Men can be punished for past sins when they cross a bridge or any similar dangers. 2. Rav wouldn’t cross river on boats with non Jew so as not to be “grabbed” with him. Shmuel did the opposite bc angels don’t control two nations at once. 3. R Yannai wokld check the boat before crossing. A persons should not position themselves in danger. R zeira wouldn’t walk by olam trees on very windy days. 4...

1. Hillel was more patient and humble than Shammai. It happened with 3 stories of potential converts, one who only believed in written Torah, one who wanted to learn Torah on one foot, and one one who wanted to be a Kohen gadol- Shammai pushed them away and Hillel converted then with great patience. 2. There were 2 people who made a bet if one of them could anger Hillel. One tried angering him By...

1. Extinguishing a candle is a melocho on Shabbos. But putting it out for a reason besides making the candle itself better would be a מלאכה שאינה צריכה לגופה- that’s a dispute between r yehuda (obligated) and r shimon (exempt). Examples would be to save oil, lamp, or save a wick, so someone could fall asleep better, etc. 2. Everyone agrees it is permissible to put out a candle for a life threateni...

1. Rava explains the dispute in the mishna about using a garment as a wick for Shabbos candles to be based on whether it will light properly without charring it first. 2. There’s dispute between r yehuda and r Shimon for muktzeh. One relevant case is on Yom tov to to use broken pieces of utensils for firewood. R yehuda forbids it bc the broken shards are “Nolad”- viewed as new items that were born...

1. For tumas ohel, the only material from trees that accepts such tumah is flax. This is bc it is the only material from trees that we find is called אהל. We find flax called ohel from the mishkan where it was used as one of the 3 coverings for the mishkan. 2. Wood beams are not subject to tumas ohel even though the קרשים in the mishkan were world, bc the pasuk language is make kerashim *for* the...

Bitul on Chametz

1. When it says בגד by tzaras, it specifies wool or linen. We include any sized cloth, even 3x3 fingers width. The pasuk also includes שתי או ערב- threads unwoven. It also says בגד by tumah from dead rodents. Tana from r yishmael taught that we learn out that it is also only by wool or linen and not other materials. There’s a dispute between Abaye and Rava if R Shimon disagrees with R yishmael and...

1. Balsam oil can be dangerous with fire, as evident in the story with the mother in law who hated for daughter in law and had adorn herself in balsam oil and then get goes to fire. She burned. 2. Tevel tamei (before grain is tithed) it is forbidden to burn it for fuel. Source for this din is based on the source that Terumah tamei can be burned. The source was HaShem said to Aron I have you 2 teru...

1. The mishna outlawed burning Terumah temai oil on Yom tov for candles. This implies that on a regular day one can burn oil of Terumah that became tamei and Benefit from its burning. 2. Maaser Sheini the pasuk says לא בערתי ממנו בטמא- it is forbidden to benefit from the burning of tamei maaser. There are 3 possible sources to teach that Terumah may be different. ואני נתתי לך את תרומתיHaShem HaShe...

1. We mentioned that there is Al hanissim in davening, but what about during birchas Hamazon? It’s only drabanan so maybe there’s no need but there is an aspect of פרסומי ניסא. The Gemara says one doesn’t “need” to, but if done, it should be during נודה and not רצה. 2. Once it’s concluded that one doesn’t have to say al Hanisim in Birchas Hamazon, the Gemara wonders about yaalev vyavo during Birch...

1. The Gemara concludes that the bracha is להדליק candles of Chanukah bc the lighting is the mitzvah and therefore if a child lit the menorah the mitzvah would not be fulfilled. 2. Women are obligated in Chanukah lights bc they were part of the miracle 3. Even a guest needs to light Chanukah candles. They can also use option of contributing a little money for the oil. In addition, if someone is li...

1. Chanukah light placed higher than 20 amos is no good, (normal line of vision does not extend beyond that point so it won't publicize the miracle) 2. The pit the brothers threw Yosef in was empty of water, but filled with snakes and scorpions. 3. Menorah should go on the left side of the doorway, (when one is entering) so the mezuzah is on one side and the menorah on the other. 4. The pasuk indi...

1. Even with “bad” wicks that you can’t light with, you may use them as part of a big bonfire. 2. Can’t use שמן קיק- kik is either oil extracted from a certain bird, cottonseed oil, or oil from kikayon plant from Yonah. 3. If one adds some good oil into these bad oils, can you light with the mixture? It’s a dispute in the Gemara, and the issue is whether the Rabbis enacted a further decree outlawi...

1. One is not allowed to keep food that is still cooking when Shabbos begins on the fire (bc they may come to stoke the coals). However, once the food has reached בן דרוסאי- edible state, it is permitted (bc it’s less likely someone would stoke the coals). The equivalent with bread is if the bread turns crusty on its top that faces the fire it is ok to keep it on the fire. (R Eliezer requires it t...

1. According to Beis Shammai, one has to make sure his chametz is destroyed before Pesach. So it’s not enough to sell it to a non Jew unless we’re confident he’ll consume it before pesach. But beis Hillel says it’s fine if one removes it from his possession. 2. We are not allowed to feed animals on Shabbos unless they are our own, with the exception of dogs. Similarly, we can feed indigent non Jew...

Why marror is after pesach

How we got to Mitzrayim to begin with 

1. There’s a dispute between רבי and ר יוסי regarding the laws of לישה- kneading on Shabbos. Rebbe holds the melacha is even with just mixing the flour and water. R Yosi holds the melacha is only when one manually kneads the two. R Yosi simply holds that manual kneading is the forbidden act and it is true even with materials that mix well by themselves, like ashes with water or dyes. 2. Acc to רבה...

1. A dead body transmits tumah to any sized material directly above it. There’s another law that when there is a “roof” above a dead body, at least one tefach thick, then the tumah spreads to anything under the same roof. By rabbinic law, one of the 18 decrees, a roof can be even something that is 1/3 of a tefach. 2. There is a law in tumah for foods that it cannot accept tumah unless it first bec...

People are earthenware keilim

1. We learned yesterday that the Rabbis instituted Tumah on glass bc it comes from sand and resembles earthenware. Earthenware accepts Tumah only from the inside and not from its outside and yet we find that glass accepts tumah from its outside. This is because glass is also like metal in the sense that it can be fixed if it becomes broken, and the Rabbis therefore gave it the law that it accepts...

1. We mentioned that Hillel and Shammai argued in 3 places, so the gemara explores them. The amount of dough obligated in tithing challah for the Kohen. Shammai says one kav. Hillel says two kav. The Halacha is compromise view of 1 and a half kav. This is equal to the amount of manna each Jew are a day in the desert. Second dispute is about amount of drawn water invalidates a mikveh. Third dispute...

1. Lets give an intro to understand the 18 decrees of beis Shammai and beis Hillel. By Torah law, a person or vessel does not become tamei from a secondary Tumah. (Dead body is avi avos hatumah, contact with dead body makes av hatumah. Then something with contact with that becomes a rishon. That’s the farthest tumah can extend to a person. Or, for example, a dead animal or rodent is an av hatumah,...
